Re: "BP asks to abandon plugged containment dome in Gulf," A-24, Oct. 28. Recently, BP reported oil sheen in the vicinity of its Deepwater Horizon disaster. The Coast Guard and BP blame the failed containment dome that BP discarded near the site. BP said it plugged the leak but wants to leave the dome on the bottom, claiming that removing it presents environmental and safety risks.

Of course, BP hasn't released any information to the public about what risks removal poses. And there is no assurance that this piece of BP garbage will not start to leak again.

It is estimated that the dome leaked about 100 gallons per day or 36,500 gallons per year -- not a small amount of oil. Although I know that there are natural oil seeps in the Gulf, this is man-made pollution that can be eliminated. Continuing leaks pose a risk to marine life on the ocean bottom and at the surface.

Hasn't BP done enough harm? And, more importantly, isn't anyone going to require the company to fully clean up the mess it has made? Or are we simply going to sit by and allow the Gulf to remain BP's sacrifice zone.
